The cause appears to be related to the size of the file, the inidivual episodes being downloaded are >200Mb for ~25 mins which seems much larger than previously. No forwarding links are in place, and this has worked fine for months until very recently. Any an all assistance would be greatly appreciated!

Our engineers were able to get to the bottom of this and have deploy a fix for it. Your audience should now be able to listen & download to the episodes properly again.
Thanks for hanging in there, much appreciated!
